1. INTRODUCTION
Accurate measurement is an important aspect of manufac-
turing. Advancement of equipment and plant engineering
technology requires higher performance and more versatile
instrument functions.
The Ashcroft model 50 HPS High-Purity pressure gauges are
similar to ordinary instruments, yet have been assembled
under a significantly different process where treatment,
control, and inspection are rigidly maintained. This manual
describes the basic operation of this product for the semi-
conductor industry. Adhering to the following instructions
will ensure their proper and effective application.
Before Using the Pressure Gauge
It is highly recommended that this instruction be thoroughly
reviewed to prevent improper instrument handling and/or
implementation. Consult Ashcroft on related topics not cov-
ered within this document.
Warranty
Instruments are repaired or replaced, at no cost, if deter-
mined to be within the 1-year warranty period and non-con-
forming in accordance with defects due to design or manu-
facture by Ashcroft.
Please note that the following instances are excluded.
1 Delivered products are disassembled, altered, parts
replaced, or where any new function is added by the user
or any third party.
2 Directions described within the instruction manual or cat-
alog have not been observed.

2. APPLICATION
3. TRANSPORTATION, STORAGE, UNPACKING PRECAUTION
The instrument may incur damage if dropped/impacted.
3 Non-conformance is caused by deterioration due to use,
natural disaster, fire or other force majeure events.
D Secondary damage caused by the non-conformance of
the products including the above.
Regardless of recognized mishandling, any apparent evi-
dence of deformation, abrasion, burnout or other identi-
fied issue shall be excluded from the warranty scope with

Definition of Safety Terms
Safety precautions within this manual have been classified
as follows:
DANGER - Ignoring this warning may result in serious injury
or death.
WARNING - Ignoring this warning may result in serious
injury or death.
CAUTION - Ignoring this warning may result in the material
damage and render instrument performance defective.
This pressure gauge has an electropolished wetted sur-
face for measuring materially-compatible gas pressure (EP
grade). The pressure gauge is fabricated in accordance with
high cleanliness and tightly sealed standards. Therefore,
the models 50 HPS High-Purity pressure gauges are ideally
suited for pressure measurement within the semiconductor
production process, etc.
WARNING
The instrument's pressure element is a bourdon tube.
Do not use the pressure gauge with the wetted mate-
rial exposed to any corrosive gas or atmosphere.
Additionally, it is industry practice for the gas detector's
to be installed within the same environment; this will
provide an alert to escaping gas that may adversely
affect the human body and/or equipment
3.1 Transportation
Units should be handled the same as electronic or test mea-
surement instruments. Be very careful not to apply vibration
to the pressure gauge during transportation.
Never hit or drop the pressure gauge.
CAUTION
3.2 Storage
Store in a temperature-controlled environment free from
dust, humidity, and vibration. Prevent temperature variances
as this may result in condensation developing in the product.
3-3 Unpacking
Handle product with great care during unpacking.
Verify the product has not been damaged and that the
instrument fulfills the required specifications. Please contact
the dealer or Ashcroft if an issue exists.
